Dan, I realize new doesn't mean it's not a possible; just stated that way because I've already double checked those items, and by mentioning new that let's you know ahead of time they're basically not going to be energy hogs to start with.
Fridge is doing fantastic; so nice to finally have one that hardly runs at all. Dryer has also been checked out. No dehumidifier.
Planning now to use induced current meter one circuit at time, running individual items like the spa heater and water garden pump to see if they may have something to do with it.
I doubt I'll find anything, but by having done all this I'll have more ammo on my side when I go back to elec. co. about changing meter out.
